Newcastle boss Alan Pardew is hoping Jonas Gutierrez's decision to sign a new long-term contract will persuade skipper Fabricio Coloccini to do the same.

The 28-year-old Argentinian midfielder this week put pen to paper on a four-year deal and Pardew, who had hoped to persuade Kevin Nolan, Jose Enrique and Joey Barton to stay on Tyneside this summer, is keeping his fingers crossed that compatriot Coloccini will follow suit.

The central defender will lead the Magpies into Barclays Premier League battle at Wolves tomorrow hoping to extend their eight-game unbeaten start to the season.

Pardew said: "Of course Colo is on the agenda, there is no doubt about that. He's had a terrific start as captain.

"We have a different look to the team and he is part of that, and securing Jonas will only help in the process of trying to secure Coloccini."

Mick McCarthy believes persuading striker Kevin Doyle to sign a new contract reinforces his belief that Wolves are not a selling club.

Doyle yesterday put pen to paper on a new four-year contract to end constant speculation about his future.

McCarthy revealed summer capture and new skipper Roger Johnson had asked if Wolves would sell their best players - including Doyle and winger Matt Jarvis - before moving from Birmingham.

The Wolves manager said: "When I was taking to Roger Johnson in the summer, his worry was Doyle and Matt Jarvis might go.

"I was honest and straight with him and I said 'if Man United came in for them, we'd have to sell them'.

"But Jamie O'Hara wouldn't have come here (from Tottenham) if we were selling our better players. We want to re-sign them and keep them."

Wigan boss Roberto Martinez is wary of the threat of Charles N'Zogbia, but does not think he is at his best yet with Aston Villa.

N'Zogbia will face his old club tomorrow for the first time since making a summer switch to Villa Park.

Martinez said: "He is only happy when he is on the pitch and when you get players like that it is just a matter of time before they are successful.

"But it is going to take time to be himself. I hope he hits his best moment of form further down the season.

"If on Saturday he can have a quiet moment it would be much appreciated."
